第二台显示器上的监听键和全屏幕

Question

我有两台监视器。如果我运行我的项目，它会出现在主显示器上。我可以通过以下方式调整窗口大小并使其全屏： - >点击右上角的全屏按钮 - >将其拉到屏幕的顶部

像往常一样为微软-视窗。

但是，如果我在第二个窗口中拉我的应用程序，这将改变。通过点击全屏图标，或将其拉至顶我会收到以下错误消息：

这里是一个小样本只是为了证明我的问题：

from kivy.config import Config 
Config.set('kivy', 'exit_on_escape', '0') 
from kivy.app import App 
from kivy.uix.label import Label 
from kivy.uix.boxlayout import BoxLayout 
from kivy.uix.button import Button 
from kivy.uix.popup import Popup 
from kivy.core.window import Window 
from kivy.properties import ObjectProperty, ListProperty, StringProperty 
from kivy.logger import Logger 


class ChildApp(App): 


    def __init__(self, sys_path_list=None): 
     super(ChildApp, self).__init__() 
     # Hotkey 
     self.superkey = [] 
     text = StringProperty() 
     keyboard = Window.request_keyboard(self._keyboard_released, self) 
     keyboard.bind(on_key_down=self._keyboard_on_key_down, on_key_up=self._keyboard_released) 


    def _keyboard_released(self, *args): 
     self.superkey = [] 


    def _keyboard_on_key_down(self, window, keycode, text, super): 
     if 'lctrl' in self.superkey and keycode[1] == 's': 
      Logger.info('DO SOMETHING') 
      self.superkey = [] 
      return False 
     elif 'lctrl' not in self.superkey and keycode[1] in ["lctrl"]: 
      self.superkey.append(keycode[1]) 
      return False 
     else: 
      Logger.info("key {} pressed.".format(keycode)) 
      return False 


    def build(self): 
     Window.bind(on_request_close=self.on_request_close) 
     return Label(text='Child') 


    def on_request_close(self, *args): 
     Logger.info('Are you sure?') 
     return True 


if __name__ == '__main__': 
    ChildApp().run() 

我在添加键盘收听功能之前，它能够在两台显示器上全屏显示。 你能告诉我如何在两台显示器上全屏显示吗？

我编辑了以下文件的行＃1141：

C：\ Python34 \ LIB \站点包\ kivy \核心\ window__init __ PY

行：

targettop = max(0, target.to_window(0, target.y)[1]) if target else 0 

编辑到：

if target and 'to_window' in dir(target): 
    targettop = max(0, target.to_window(0, target.y)[1]) 
else: 
    targettop = 0
